Global Archive of Ortho-rectified Landsat DataEntry ID: ORTHO_LANDSAT
Abstract: Recognizing the need to provide high-resolution satellite data to the scientific community, NASA's Commercial Remote Sensing Program Office, has been working to assemble the first wall-to-wall global coverage of ortho-rectified Landsat Thematic Mapper and Multi Spectral Scanner data to support scientific studies. In August of 1998, NASA contracted with MDA (then EarthSat) to produce positionally ... accurate orthorectified Landsat Thematic Mapper and Multispectral Scanner imagery covering the majority of the Earth's land mass. Scene selection, acquisition, and processing of Landsat data is done by MDA Federal Inc. (http://www.mdafederal.com).
There are two separate product lines developed from the GeoCover Project:
1. EarthSat GeoCover-Ortho (Orthorectified) products are the actual satellite images derived from Landsat TM scenes and are the most accurate, commercially available base maps of the world.
2. EarthSat GeoCover-LC (Land Cover) products consist of a medium resolution land cover database, prepared from consistently orthorectified Landsat Thematic Mapper (TM) imagery.
The Landsat imagery used to create the GeoCover-Ortho products have been hand selected to provide the lowest cloud cover and highest quality data possible. The Landsat TM imagery are all circa 1990 and have been selected as close to the local peak growing season as possible. The imagery have been collected from the majority of the Landsat foreign ground stations, as well as from the US Government's EROS Data Center. Never before has such a complete collection of high quality Landsat imagery been assembled for processing and analysis. The GeoCover-Ortho image map data sets represents a milestone in the use of Landsat digital imagery to map and study the Earth's surface.
